Description
- The present invention relates to a water-repellent composition.
- Conventionally, fluorine-containing water- and oil-repellent agents comprising a fluorine compound have been known. These water- and oil-repellent agents exhibit good water- and oil-repellency when used for a substrate such as textile products.
- Recent research findings, for example, an EPA report: "PRELIMINARY RISK ASSESSMENT OF THE DEVELOPMENTAL TOXICITY ASSOCIATED WITH EXPOSURE TO PERFLUOROOCTANOIC ACID AND ITS SALTS" (http://www.epa.gov/opptintr/pfoa/pfoara.pdf), have shown an increasing concern about a load on the environment caused by PFOA (perfluorooctanoic acid) which is one of long-chain fluoroalkyl compounds. On April 14, 2003, EPA (United States Environmental Protection Agency) announced the enhancement of scientific research on PFOA.
- Meanwhile, Federal Register (FR Vol. 68, No. 73/April 16, 2003 [FRL-2303-8], http://www.epa.gov/opptintr/pfoa/pfoafr.pdf), EPA Environmental News FOR RELEASE: MONDAY APRIL 14, 2003 EPA INTENSIFIES SCIENTIFIC INVESTIGATION OF A CHEMICAL PROCESSING AID (http://www.epa.gov/opptintr/pfoa/pfoaprs.pdf), and EPA OPPT FACT SHEET April 14, 2003 (http://www.epa.gov/opptintr/pfoa/pfoafacts.pdf) have disclosed the possibility of generation of PFOA when a telomer is decomposed or metabolized (the telomer means a long-chain fluoroalkyl group). They also have said that telomers are used for various products having water- and oil-repellency and antifouling properties, such as foam fire extinguishers, care products, washing products, carpets, textile, paper and leather. There is the concern that fluorine-containing compounds are accumulated in the environment.

Furthermore, conditions of polymerization reaction may be optionally selected. Such polymerization method includes a solution polymerization, a suspension polymerization and an emulsion polymerization. The emulsion polymerization is preferred.
- As long as the present composition is in the form of an aqueous emulsion, the method for producing the polymer is not limited. For example, the polymer is produced by the solution polymerization and then the solvent is removed and a surfactant and water are added thereto to give an aqueous emulsion.
- For the solution polymerization, a method may be used, in which a monomer is dissolved in an organic solvent in the presence of a polymerization initiator and after substitution with nitrogen, the solution is heated and stirred at 30-120°C for 1-10 hours. Examples of the polymerization initiator include azobisisobutyronitrile, benzoyl peroxide, di-t-butyl peroxide, lauryl peroxide, cumene hydroperoxide, t-butyl peroxypivalate and diisopropyl peroxydicarbonate.

- To obtain an aqueous dispersion of polymer having excellent standing stability, it is desirable that monomers are formed into fine particles in water and then polymerized using an emulsification apparatus such as a high pressure homogenizer or an ultrasonic homogenizer, which can produce a high crushing energy. Furthermore, various anionic, cationic or nonionic emulsifiers may be used as an emulsifier, in an amount of 0.5-20 pbw, based on 100 pbw of the monomer. It is preferable to use an anionic and/or a nonionic and/or a cationic emulsifier. When monomers are not completely compatible, a compatibilizer capable of thoroughly compatibilizing those monomers, for example, a water-soluble organic solvent or a low molecular weight monomer, is preferably added. Addition of the compatibilizer improves emulsifiability and copolymerizability.
- Examples of the water-soluble organic solvent include acetone, methyl ethyl ketone, ethyl acetate, propylene glycol, dipropylene glycol monomethyl ether, dipropylene glycol, tripropylene glycol and ethanol.

For example, the amount of the medium may be 5-99.9 wt.%, in particular, 10-80 wt.%, based on the water-repellent composition.
- The concentration of the polymer may be 0.01-95 wt.%, and for example, 5-50 wt.%, in the water-repellent composition.
- The present composition may be used as an external treatment agent (surface treatment agent) or an internal treatment agent.
- When the present composition is in the form of the external treatment agent, the composition may be applied to a substrate to be treated by a conventionally known method. Usually, the composition can be used in a method wherein the water-repellent composition is diluted by dispersing in an organic solvent or water, and the resultant is applied to the surface of the substrate to be treated by a known process such as dip coating, spray coating or foam coating, and dried. Alternatively, if necessary, the composition may be applied to the substrate together with a suitable cross-linking agent (e.g., a blocked isocyanate) and cured. Furthermore, e.g. an insecticide, a softening agent, an antibacterial agent, a flame retardant, an anti-static agent, a coating fixative, or a wrinkle-resistant agent may be added to the present composition to be used in combination. The concentration of the polymer in a treatment liquid to be brought into contact with the substrate may be 0.01-10 wt.% (in the case of, in particular, dip coating), and for example, 0.05-10 wt.%.
- Examples of the substrate to be treated with the treatment agent composition (the present composition) include textile products, stone materials, filters (e.g., electrostatic filters), dust masks, parts of fuel cells (e.g., gas diffusion electrodes and gas diffusion backings), glass, paper, wood, leather, fur, asbestos, bricks, cement, metal, oxide, ceramic products, plastic, coated surfaces and plaster. Examples of the textile product include various items. Examples of the textile product include animal and plant natural fibers such as cotton, hemp, wool and silk, synthetic fibers such as polyamide, polyester, polyvinyl alcohol, polyacrylonitrile, polyvinyl chloride and polypropylene, semi-synthetic fibers such as rayon and acetate, inorganic fibers such as glass fiber, carbon fiber and asbestos fiber, and a mixed fiber thereof.
- Textile products may be in the form of e.g. fiber or fabric.
- The present composition may also be used as a soil resistant agent, a peeling agent, or a release agent (e.g., an internal release agent or an external release agent). The surface of a substrate, for example, can be easily peeled off of another surface (another surface of the substrate, or the surface of another substrate).
- The polymer may be applied to a fibrous substrate (e.g., a textile product) by any known method for treating a textile product with liquid. When the textile product is a fabric, the fabric may be dipped in a solution, or a solution may be applied to or sprayed on the fabric. The textile product treated is dried and preferably heated at, for example, 100-200°C for water-repellency to be exhibited.
- Alternatively, the polymer may be applied to the textile product in a cleaning method. The polymer may be applied to the textile product, for example, during washing or in a dry cleaning method.
- The textile product to be treated is typically a fabric, including a woven fabric, a knitted fabric and a non-woven fabric, a fabric in the form of clothing, and a carpet. The textile product may also be a fiber, a yarn or an intermediate textile product (e.g., a sliver or a roving). Materials of the textile product may be a natural fiber (e.g., cotton or wool), a chemical fiber (e.g., viscose rayon or lyocell), or a synthetic fiber (e.g., polyester, polyamide or acrylic fiber), or may be a mixture of fibers (e.g., a mixture of the natural fiber and the synthetic fiber). It is preferable that the textile product is the carpet.
- Alternatively, the fibrous substrate may also be a leather. To make the leather hydrophobic and lipophobic, an aqueous solution or an aqueous emulsion of the polymer produced may be applied to the leather at various stages of leather processing, for example, in the period of wetting processing of the leather or finishing of the leather.
- Alternatively, the fibrous substrate may be paper. The polymer produced may be applied to the paper which has been previously prepared, or may be applied to the paper at various stages of paper making, for example, in the period of drying of paper.
- The "treatment" means application of the treatment agent to the substrate to be treated by, for example, dipping, spraying, or coating. The treatment allows the polymer, which is the active ingredient of the treatment agent, to penetrate into the inside of the substrate and/or to adhere to the surface of the substrate.
- When the water-repellent composition is in the form of the internal treatment agent, the water-repellency can be given to a resin, for example a thermoplastic resin, by adding the composition to the resin. The water-repellent composition may be used when producing a molded article of the resin.
- The liquid medium is removed from a liquid (a solution or a dispersion) comprising the polymer to give the polymer. For example, the dispersion of the polymer (an aqueous dispersion or a dispersion in an organic solvent) is subjected to re-precipitation with water or an organic solvent and then the resultant is dried to give the polymer.
- A molded article can be produced by, for example, a method comprising preparing a resin composition by mixing the resin and the polymer and molding the resin composition. It is preferable that a molded article is produced by melting and kneading by using, for example, an extruder.
- In general, the thermoplastic resin and the polymer are compatible in a molten state. Kneading can be performed by a conventionally known method using, for example, a single screw extruder, a twin screw extruder or a roll. The resin composition obtained as described above is e.g. extrusion-molded, injection-molded, compression-molded, blow-molded, or molded by a press. The resin composition is molded into molded articles of various shapes. The resulting molded article may be further heated in, for example, an oven or a drying furnace after molding processing. The molded article may have a single layer or multilayers of 2-10 layers, and for example, 3-5 layers.
- The molded article can be used for the application in which a thermoplastic resin is used, more specifically, an application in which the resin preferably offers high convenience of wiping off stains and excellent scratch resistance. Examples of the application of the molded article include automobiles (exterior and interior parts) (e.g., bumpers, instrumental panels, door trims), household electric appliances (e.g., washing machines, refrigerators)(including housings, doors, trays and vegetable compartment containers in refrigerators), various cases, building materials (interior materials and parts) (e.g., handrails, wall papers, tables, chairs, toilet sheets and sheet covers, bath tubs), electronic appliances (e.g., housings of smartphones), drainage ditches, pipes, tableware, floor materials, gasoline tanks, fuel hoses and OA equipments. Among them, automobile interior parts, interior parts of household electric appliances and building materials are more preferred.

Water-repellency of the fabric treated thus was evaluated, based on the spray test according to JIS-L-1092 (AATCC-22). The result is described as water-repellency No. as shown in the following table. A higher score indicates a higher level of water-repellency.

The diluted liquid is placed in a pad whose temperature can be adjusted to 40°C. A polyester fabric having a width of 20 cm and a length of 80 cm in a loop is continuously treated through a mangle at a mangle pressure of 0.4 MPa for 1 hour. The gum up ratio is determined by the following equation.
(Amount of gum up on mangle) = (Weight of polyester fabric before treatment + weight of solid content of diluted liquid before treatment) - (Weight of polyester fabric after treatment + weight of solid content of diluted liquid after treatment) (Gum up ratio) = 100 × (Amount of gum up on mangle) / (Weight of solid content of liquid before treatment) - A gum up ratio of less than 4% shows suppression of gum up (good processing stability).
